HINGE.

SPECIFICATION forming part of Letters Patent N 0. 699,727, dated May 13, 1902.

Application filed May 22, 1901. Serial No. 61,364. (No model.)

To all whont it may concern:

Be it known that we, JOSEPH M. UPTON, of Atlantic, and WVILLIAM S. GRAY, of Braint-ree, in the county of Norfolk and Commonwealth of Massachusetts,citizensof theUnited States, have invented a new and useful Improvement in Equalizing Truss-Hinges, of which the following is a full, clear, and exact description, reference being had to the ac- IO companying drawing, forming a part of this specification, in explaining its nature.

The invention relates to the herein-described hinge, which is especially adapted for heavy doors for any use and which is in- I5 tended not only to strengthen the door, but

to also assist in the preliminary and easy hanging of the door and in removing its sag when required; also, in preventing the same.

We will describe the invention in conjunction with the drawing forming a part of this specification, in which the figure is aview in elevation of the parts of the hinge applied to a door-frame and door.

Referring to the drawing, the hinge com- 2 5 prises the bnttsA A of any desired construction and which are bolted or otherwise fastened to the door frame or support. Each of them is arranged to provide two bearings for the pintle, which connects it with the other member of the hinge. These bearings are lettered a a in each butt, and they are separated from each other by a space a of sufficient width to receive the end of the other member of the hinge and also the adjustingnuts upon the pintles herein described.

The upper movable member of the hinge, which is attached to the door, comprises the barB of varying length, as the size or weight of the door may require,butpreferably shorter than that shown in the drawing. Through a hole in the inner end of bar B extends the pintle 1), connecting the same with the butt A, while from its outer end, integrally fastened thereto, extends the truss-bar B diagonally upward and backward to the point I), which will bring it near the upper inner corner of the door and from thence downward and backward to bring its end Z1 over the top of the upper bearing a of the butt A.

This truss-bar B is not attached throughout its length to the door, but only where its end forms the integral connection with the bar B. This integral connection with the hinge member is not necessary, but only furnishes a more feasibleconstruction. Anyotherlneans by which the bar B may be attached to the door,so as to admit of a certain amount of springing or yielding, would sutiice. Being thus hung or suspended when proper force is applied, as by a straining device connecting the bar B- with the lower hinge member or the door, the bar B would naturally spring or be drawn down toward the bar B. Instead, however, of the bar B springing down, which of course it cannot do by reason of its resting on the solid butt at 19 an indirect action occurs, and the bar B, or rather the door, is drawn up and so permitting of the adjustment, as will be described later. The end b of the bar B rests upon the upper'surface of the butt, forming a main hearing b of the hinge and of the door, and in said end 17 is a hole, through which the pintle b extends, the pintle having a headed end If to rest upon its upper surface b There is used with the butt A the hinge member 0. This is also of varying extension,

, preferably shorter than as shown in the drawing. It comprises a straight bar 0, having at its inner end a hole, through which the pintle c, attaching it to the butt, extends. From the outer end of this bar and integral with it there extends a truss or brace'bar G which is shaped to first extend downward to the point 0 near the bottom or lower outer corner of' the door and then backward and upward to the inner end of the bar 0, where it is integral with it.

Both the upper and lower door members of the hinges, it will be seen, have what might go be called a truss construction -that is, the straight portion of each is reinforced by a bar having a truss action, and which stiffens each member and also serves to reinforce and stiffen the door, as well as assisting in its adjustment. It will be seen'that the portions of each member which form the trusses bear opposed relations to each other and that they are connected at their apexes'or. points 0 and b by a brace and tie rod D, which, rec

in effect, extends downward across the door from near its upper inner corner to near its bottom or lower outer corner. This tierod D is made in two parts 61 d. The part d is pivoted at its upper end to the truss-bar B. The part d is pivoted at its lower end to the truss-bar C The contiguous ends of the two parts are slightly separated from each other and have screw-threads for receiving a turnbuckle d by means of which the said rod may be shortened or extended, and thus be made to serve as a means of draft or extension between the bar or arm B and the lower hinge member or the door, for the tie-rod D at its lower extremity could be pivoted directly to the door and still permit of the desired actions. The construction indicated, however, is the most feasible. Now when the tie-rod D isshortened by means of draft upon the turnbuckle the door would rise on its pintles. The bar in arm B could not be drawn, down, for, as before described, it sets firmly on or against its butt; but it yields or springs sufficiently to permit of the door being drawn up or a vertical action obtained. If the door was so fixed that no vertical action could be had along its inside edge when stress is applied to the turnbuckle, a torsional action would be had. In other words, the outer portion only of the door would be raised or adjusted. Thus the tie-rod D serves not only to so tie the two members of the hinges together as to add to the strength of each and to the strength of the door, but it also acts as a means for the adjustment of the door with respect to the door-frame, assisting when hanging the door in lifting the same,so that it may swing freely in its frame-opening, as will be described later, also assisting in moving the outer portions of the door vertically with respect to the inner ones with such torsional movement, for instance, as would be necessary for removing sag from it or rendering other necessary adjustment.

The lower pintle c is held stationary in the bearings of the butt A in any desired way. The portion between the butt-bearings is provided with a screw-thread 0, upon which the adjusting-nut c and the check-nut c are held. The inner end of the lower hinge member 0 bears upon the adjusting-nut, which forms the second bearing of the door and which cooperates with the main or upper bearing above spoken of. The upper pintle b is also held stationary in its bearing in any desired way. It has a threaded section 5 below the upper bearing a and upon which is a nut 17 and a check-nut b". The nut bears against the lower end of the said upper bearing a and serves to hold the end 12 of the truss-bar B firmly on its rest-bearing at the upper end of the pintle-bearing a. The material function of the nuts, however, is when the nut b is moved down against the bar B and the nut b becomes a check-nut, preventing any upward movement of the door along the vertical inside edge. Thisdown ward movement of the nuts is employed only when a torsional movement is given to the door to remove sag or otherwise by the turning of the turnbuckle of the tie-rod D.

In hanging the door, although various methods are possible through the construction, the following is the most expedient: The door is first rested in its casing, so that the ends of the bars B and 0 lie in their respective frameopenings, the end of B resting upon the upper surface of the rest a of the upper hinge, while the end b of the bar B rests upon the upper surface of the rest a. The pintles are then inserted,with the adjusting-nuts, respectively, on the threaded surfaces 12 and c, the nuts Z9 11 of the upper hinge being turned up against the lower surface of A, holding the end I) of the truss-bar B firmly on the restbearing a at the upper end of the pintlebearing a, and so leaving a sufficient opening for the upward vertical movement of the end bar B along the pintle, the nuts b b of the lower hinge being at this time naturally placed upon the upper surfaces of the rest a of the lower hinge. The door is now ready to be raised, so as to hang free from the base of its casing. This is done by turning the turnbuckle on the tie-rod D, the door being raised by this adjustment. The bar B springs sufficiently to allow of the action, while the under surface b of the end b maintains a proper; relation to its'rest a by reason of the angular construction of the bar B. The nuts on the pintle at c are then turned upward to provide a rest for the bar 0. Thus the door is expeditiously hung, and so adjusted as to make sag well nigh an impossibility. If, however, it becomes necessary to true the door for rectifying sag or otherwise, it can be done without removing the door from its butts by means of the turnbuckle, the adjusting-nuts b b first being turned downward against the upper surface of the bar 13 to prevent any upward movement of the inside edge of the door before the turnbuckle is turned. Thus the outer edge of the door is raised by the administration of a torsional strain and the door trued. In fact, by means of the turnbuckle along or in conjunction with the pintle-nuts the door is capable of any adjustment.

It will be seen that the upper. hinge member has two swinging hearings on the pintle and one rest-bearing on the butt and that the lower swinging bearing is movable vertically on the pintle. It will also be seen that the lower hinge member has a swinging bearing that is vertically adjustable on the pintle and that its rest is also vertically adjustable on the pintle.

As regards the springing of the bar 13, inasmuch as the door would naturally be raised only so far as to swing free and clear the spring of the bar B would hardly be perceptible to permit of this, and fastened as the bar or arm is to the bar B and mounted as it is on the butt and pintle the spring or the bar or arm would hardly be outward, but with shear motion relatively to the bar B. This springing or yielding of the bar Bis perhaps IIO not so essential to the torsional adjustment of the door as it is to its hanging, for in the former adjustment the nuts being screwed down against the hinge member B prevents any upward movement of the door, so that the position of the bar B with the bar B is relatively preserved, and the screwing up of the turnbuckle results onlyin adjustment of the outer portion of the door.

Having thus fully described our invention, we claim and desire to secure by Letters Patent of the United States- 1.
